RAZOR WITH BLADE-ADAPTER f,

' Jacob M. Moses, Baltimore, Md. I ApplicationOctober 25, 1934, SerialNo:.750,001

5 Claims. (01. 30-12) This invention relates torazors of the wafer bladetype, and it has for its general object the provision of a bladeassembly including an adapter, which not only enables the'same style ofblade to be usedeither with the straight or hoe type frame, butco-operates with the blade so as to leave the margins uniformlyunsupported back of the cutting edges for such distance as to permitslight yield or vibration of the blade as it engages the beard. Itis-known that a blade which is clamped so close to;the cutting edges asto be unyielding, engages the beard with all the inertia of the mass ofthe frame, and if not extremely keen, causes painful pulling ofthesbeard. It is also known that a razor that sings gives the smoothestshave and this singing is produced by vibration of the edge portion .oftheblade.

- Specifically stated, the object of the invention istheprovision of anadapter, inter-fitting with a wafer blade and with the frame, forholding the blade in place,,and interposing a portion of itself betweenmedial portions of the blade and the clamping means between which theblade is constricted, holding the marginal portions of the blade freefrom the clamping pressure so that they can yield in the manner setforth.

A further object of, the invention is to provide means for insulatingthe 'blade from metallic contact with other parts of the razor, so thatelectrolytic action will be averted and the razor may be put away wetwithout being subject to corrosionfrom this cause;

Other objects of the inventionwill appear as the following descriptionofpreferred and prac tical embodiments thereof proceed.

In the drawing which accompanies andforms a part of the followingspecification and through Figure 2 is a section taken along the line2-2,

' Referring in detail tothe several figures, the razor shown in'Figure 1is of the straight? type,v the frame 1 of which is disclosed in theapplication for patent Serial 'No. 677,507, by Ernest T. Fry, and filedJune 24, 1933. It comprises a handle 2'and integrally extending plates 3and 4having a narrow transverse space between them adapted to receivethe razor blade. In the Fry invention, theplates 3 and 4 may be rigid orslightly resilient so as to increase their pressure upon the bladewhenthe. razor is pressed against the skin. The blade isa friction fitin the Fry invention and is provided with a rib fitting into a slot 5inthe frame for holding the blade against lateraldisplacement. Such ablade as the Fry application discloses and describes is difficult tomanufacture.

The present invention substitutes'therefor a two-part constructionrepresented by the blade 6 shown in Fig. 3. and the'adapter 7constituting Fig.v 4. The blade 6 is a flat element having a. simpleslot 8 stamped therethrough inalongitudinal direction, andis'thereforeeasy and inexpensive to manufacture. The adapter- 7 which may be ofmetal, celluloid or any other suitable material is formed .l with alongitudinal rib 9 adapted to extend through theslot 8 in the blade andthen, in association with the blade the rib 9 is designed to projectthrough the slot 5 in the framewhen the bladeisinserted'in the frame.The'rib's as illustrated, is formed by folding the sheet metal blank ofwhich the adapter is com posed, but this construction is notmandatoryfor the rib may, if desired, be a separate member welded or otherwisesecuredto a base 10 of the adapter. One must not be misled into theimpression that the blade and adapter area mere twopart equivalent ofthe ribbed blade shown in the Fry application for while the rib 9 of theadapter 7 does co-operate with the slot 5 in the frame to secure theblade inthe razor, a new and important function is served 'by thepresent invention which is not performed by'the Fry construction.

It will be observed by comparing the width of the adapter with that ofthe blade in Figures 2 and 5 that the base 10 of the adapter is narrowerthan the blade and that the blade rests upon the base of the adapterwhen the couple is in position within the razor. Thus, as is indicatedin Figure 2, the base of the adapterelevates the blade from the innerface of the underlying plate 4 and keeps the marginal-portions l1 of-theblade, back of the cutting edges, free from the clamping pressure of thetwo plates 3 and 4. Thus the said margins have freedom to slightly yieldor vibrate which would not be the case in the absence of the base 10 ofthe adapter for the clamping pressure would extend very close to thecutting edges and hold the edges of the blades substantially rigid.

As has been stated, a much more smooth and comfortable shave is obtainedfrom a blade having some freedom of resiliency than with a blade whichis rigid with respect to the frame.

In removing the blade and adapter assembly from the frame shown inFigure l, the rib 9 is simply pushed out of the open end of the slot 5with the thumb or finger, carrying with it the blade. Re-insertion ofthe blade is effected by reverse movement. The blade maybe readilyseparated from the adapter for purpose of wiping the parts dry orsubstituting a fresh blade.

Figures 5 and 6 show the inventive principle adapted to a razor of thehoe type. In this form of the invention the blade 12 is similar to theblade 6 to the extent that it is provided with an'intermediatelongitudinal slot 13, but the slot intersects a central enlarged hole14. The adapter 15 too, is similar in principle to the adapter 7 beingprovided with a rib 16. The rib is however interrupted by a centralaperture 17 which when the blade is mounted upon the adapter, registerswith the hole 14 in the blade. These holes are to permit the passage ofthe coupling means which connects the upper and lower clamping members18 and 19 together. These coupling means may be of any suitableconstruction, but are here indicated as a simple screw 20 forming partof the handle 21, which passes through a bore in the clamping member 18and screws into a socket in the clamping member 19, intersecting theplane of the blade and adapter.

The clamping member 19 is provided with a longitudinal recess receivingthe rib 16 of the adapter and fixing the position of the blade. The base22 of the adapter is of such width as to terminate at a distance backfrom the cutting edges of the blade and to space the marginal portionsof the blade from the adjacent clamping member as is indicated at 23,leaving the marginal portions free to yield or vibrate.

In Figures 6 and '7 a modified adapter is shown consisting of two parts24 and 25, which may be metallic, but are preferably of non-metallicsubstance such as celluloid or bakelite. The part 24 is, like theadapter shown in Figure 4. The part 25 is flat like the blade, butsmaller in width and has a similar slot 26.

After the blade has been slipped on the adapter element 24, the adapterelement 25 is placed upon the blade with the rib of the element 24projecting through the slot 26. Thus the blade is completely isolatedfrom metal contact when'set up in a frame either of the hoe type shownin Figure 5 or straight as indicated in Figure 7.

By the use of the two-part adapter, the blade is not only equally spacedfrom both the upper and lower clamping members of the frame, but it iscushioned by the nature of the non-metallic substance of the adapter,easing the impact of the blade against. the beard. The blade being ofsmallmass soon acquires the temperature of the face irrespective ofwhether the frame is cold or hot, thus maintaining uniform temperatureconditions while one is shaving. Electrolytic action is also prevented,so that it becomes no longer necessary to dismantle the razor and wipeit dry after shaving, since it may be put away wet without fear ofcorrosion.

While I have in the above description disclosed what I believe to bepreferred and practical embodiments of my invention, it will beunderstood to those skilled in the art that the details of constructionas shown and described are merely by way of example and not to beconstrued as limiting the scope of the invention as claimed.
